Just in the past four months, since our original column on the subject, cities and states have been moving rapidly to address criticism of e-cigarette use and users by prohibiting certain sales as well as use of the devices indoors.

I’m not so sure about this. Consumers who smoke, some who don’t and others who would like to quit are experimenting with new e-cigarettes. An ever-growing number of smokers, or former smokers, are just outright switching to the new electronic smoking device that delivers nicotine but emits no smoke, only vapor.
